CA-14™ Mastic

Polyguard’s CA-14™ Mastic is a general maintenance coating for use on irregularly shaped buried steel substrates. It provides satisfactory performance when used to coat sewer piping and below-grade concrete structures. As with the CA-9™, CA-14 Mastic should be applied in multiple coats of 12 mils each allowing the previous coat to dry before application of the next coat.
